The built-in back-to-back Zener diodes have specifically been designed to enhance not only

the device’s ESD capability, but also to make them safely absorb possible voltage transients

that may occasionally be applied from gate to source. In this respect the Zener voltage is

appropriate to achieve an efficient and cost-effective intervention to protect the device’s

integrity. These integrated Zener diodes thus avoid the usage of external components.
